Honored ContributorAlmost every IP core comes with some documentation, which can be more or less complete.
If it's an IP from Altera or if the IP has been designed as a Qsys component, usually you have the HAL driver or, at least a register map to access it through IOWR/IORD. If you need to integrate a generic IP (i.e. from opencores.org) you may need to add a wrapper to interface it to Avalon bus, create a new custom device in Qsys and write the APIs yourself.
